  • The Eurasian otter(Lutra lutra) is listed as No. 330 in natural monument. To manage and conserve habitat for otters, it is critical to understand which habitat components are important for otters. The objectives of this study were to analyze otter habitat characteristics in accordance with land-cover map. We investigated otter spraints and sprainting site in Geoje Island from January to December, 2004. with GPS coordinates. The analysis of otter habitat use pattern was used by Arcview ver. 3.2 with 1: 25,000 Topology Map and field data. Otter habitat use was strongly related to sites in riparian vegetation riparian(dam or river) structures. In this study, Gucheon was a site with high coverage of riparian vegetation and unconfined channels, thus recording higher number of spraint densities than those of Yeonchocheon. Yeonchocheon was under construction at lower stream areas so that otter habitat use was limited. This study suggests that securing suitable forests and riparian vegetation zone is essential for conservation of otters.

  • Accurate knowledge of land use/land cover (LULC) features and their relative changes over upon the time are essential for sustainable urban management. Urban sprawl growth has been always also a worldwide concern that needs to carefully monitor particularly in a developing country where unplanned building constriction has been expanding at a high rate. Recently, remotely sensed imageries with a very high spatial/spectral resolution and state of the art machine learning approaches sent the urban classification and growth monitoring to a higher level. In this research, we classified the Quickbird satellite imagery by object-based image analysis of Dempster-Shafer (OBIA-DS) for the years of 2002 and 2015 at Karbala-Iraq. The real LULC changes including, residential sprawl expansion, amongst these years, were identified via change detection procedure. In accordance with extracted features of LULC and detected trend of urban pattern, the future LULC dynamic was simulated by using land transformation model (LTM) in geospatial information system (GIS) platform. Both classification and prediction stages were successfully validated using ground control points (GCPs) through accuracy assessment metric of Kappa coefficient that indicated 0.87 and 0.91 for 2002 and 2015 classification as well as 0.79 for prediction part. Detail results revealed a substantial growth in building over fifteen years that mostly replaced by agriculture and orchard field. The prediction scenario of LULC sprawl development for 2030 revealed a substantial decline in green and agriculture land as well as an extensive increment in build-up area especially at the countryside of the city without following the residential pattern standard. The proposed method helps urban decision-makers to identify the detail temporal-spatial growth pattern of highly populated cities like Karbala. Additionally, the results of this study can be considered as a probable future map in order to design enough future social services and amenities for the local inhabitants.

  • The typical characteristics of seasonal winds were studied around the Pohang using two-stage (average linkage then k-means) clustering technique based on u- and v-component wind at 850 hpa from 2004 to 2006 (obtained the Pohang station) and a high-resolution (0.5 km grid for the finest domain) WRF-UCM model along with an up-to-date detailed land use data during the most predominant pattern in each season. The clustering analysis identified statistically distinct wind patterns (7, 4, 5, and 3 clusters) representing each spring, summer, fall, and winter. During the spring, the prevailed pattern (80 days) showed weak upper northwesterly flow and late sea-breeze. Especially at night, land-breeze developed along the shoreline was converged around Yeongil Bay. The representative pattern (92 days) in summer was weak upper southerly flow and intensified sea-breeze combined with sea surface wind. In addition, convergence zone between the large scale background flow and well-developed land-breeze was transported around inland (industrial and residential areas). The predominant wind distribution (94 days) in fall was similar to that of spring showing weak upper-level flow and distinct sea-land breeze circulation. On the other hand, the wind pattern (117 days) of high frequency in winter showed upper northwesterly and surface westerly flows, which was no change in daily wind direction.

  • This study aimed to suggest the directions for the landscape protection of Sindu-ri coastal dune based on its ecological system. The study investigated ecological systems of the coastal dune followed by damage causes of coastal dune according to the land use change, and landscape value of coastal dune in the study area. In order to construct causal-effect feedback loop, systems thinking was performed. Result of this study showed that the area of coastal dune and the amount of sand are maintained by the interaction with sand beach while they are affected by wind direction, wind speed, and dune plants. It was also found that the changes of land use pattern, increasing commercial area, and planted windbreak forest damaged to the coastal dune. In addition, size of coastal dune and growing number of dune plants increased landscape value of coastal dune and tourist draw. However increasing tourists have constantly affected land use changes and have damaged to coastal dune area. In sum, planning for land use regulation, rest-year system areas, promotion and education for coastal dune, dune plants protection, and windbreak management should be taken into account for landscape protection in coastal dune.

  • 본 연구는 대구시 상업지역의 공간분포 및 계층구조 변화를 분석한 것이다. 분석기법으로 집중지수, 집중화계수 및 특화계수를 이용하였으며, 1985년$\sim$2003년의 기간을 고찰했다. 도시인구의 성장과 함께 도시적 토지이용이 증가되었다. 인구 성장 118%에 비해 상업입지량 증가율은 330%에 달하였다. 주요 상업적 토지이용은 판매업이 가장 높고 그 다음이 업무, 식품 순이다. 업종별 공간 분포의 분석에서 숙박, 의료, 운수창고 및 위락 등이 집중도가 높으며, 도시 외곽으로 갈수록 특수상업지구를 형성하였다. 판매업의 분산화가 가장 높게 나타나고 있으며, 식품, 업무도 분산 성향이 높았다. 한편 분석기간 동안, 도심부의 상업 집중 성향이 나타나고 있다. 도심핵의 공간적 확장과 함께 도심 주변지역의 상업 집중 또한 증가하는 추세이다. 도시상업의 공간구조는 단핵도시의 성격이 강화되고 있다. 그러나 내부시가지의 결절에 2계층의 중심지들이 생성되면서 다핵화의 과정에 있고, 특히 동대구역 역세권 지역은 부도심으로 성장할 잠재력을 나타내고 있다.

  • 본 연구는 요일별 시간대별 지하철역의 이용인구를 중심으로 서울시의 역세권을 유형화한 후 이를 토대로 토지이용특성과의 연관성을 살펴보았다. 역세권 유형화를 위하여 지하철역 이용특성 자료를 이용하여 요인분석을 실시하였으며, 토지이용특성과의 연관성을 파악하기 위하여 다차원척도법을 사용하였다. 본 연구의 결과는 서울시의 지하철의 역세권이 주거, 상업 및 여가, 그리고 업무중심우위으로 분류할 수 있음을 보여주고 있다. 또한 본 연구에서는 주거/상업, 주거/업무 주거/상업/업무 등의 다기능 우위를 지닌, 즉, 복합적 이용특성을 가진 다수의 지하철역도 파악되었다. 이러한 복합적 이용기능의 특성은 최근 논의되고 있는 역세권개발과 대중교통지향형 도시개발의 논의를 활성화하는 데 기여할 것으로 기대된다. 또한 기존의 역세권 유형화 연구가 대부분 도시공간구조나 토지이용특성을 가지고 계획적 측면에서 접근한 반면에, 본 연구가 지하철역의 이용패턴을 통하여 실증적으로 역세권을 유형화하고 있다는 점에서 중요한 차이가 있다.

  • This paper examined the impacts of the regional developments and dwellers behavior on the Seacoast. Seacoast features a variety of landforms which are created by the action of waves and tidal flows. The coastal landforms are found mainly in the interface between land and sea. Although erosional landforms constitute prominent landscape features as sea stack, sea arch, and rock cliff do, it is nonetheless the depositional features such as beaches, tidal flats, offshore bars, deltas, sanddunes, and coastal plains that have various ramifications for human communities. Among these, beaches and coastal sanddunes are special in that their formation is attributable to the combined action of waves, tidal flows, and winds. The main line of discussion in this dissertation is concerned with the transformation of group of beaches sanddunes along the coastline of Chungcheong-Namdo Province. To some extent, the erosion of coastal dunes has been a global phenomenon. The degradation process occurs most actively when the spring tides attack beaches, berms, and foredunes. Also involved in the transformation of coastal dunes are factors of human agency. The extent, speed, and pattern of their morphological changes are a function of land-use pattern. The reclamation of swale and the exploitation of sands as construction material and silica sand, for example, ruin the feature of coastal dunes.

  • This study is to analyse the transformation process of spatial structure of traditional small city structure in Jeollabuk-Do in the process of modern urbanization between 19th century and the year 2000. The small cities, IM-PI, YONG-AN, YEO-SAN, OK-GOO, GO-SAN, MU-JANG, GUM-MA, GO-BU, which have been local administrative center in CHO-SUN dynasty, have role of local administrative center of subdivision of country-myon, except OK-GOO. The method of this study is to investigate the transformation process of spatial structural elements of with the actual field surveys, the analysis of Gunhyun map made in 1872, land registration maps in 1910s and 2000, and various topological maps. The elements of analysis are the topological site and geographical situation conditions, the urbanized areas, the street systems, the function of streets, the focal points of urban land use, the land use systems, and the location of major facilities such as administration facilities, markets, bus terminals. The analytical point of view and the results are as follows. There is strong relationship between the transformation of internal matrix route system and the growth pattern of urbanized areas, Especially on the contrary to the matrix route with East-West direction which has the role of checking the growth of urbanized area, the South-North direction route acts as the leading line of the growth. The focal points structure of urban land use shows transformation process from the point of central space of administrative district in front of Nae-A, to the access point to administrative district or to the access point to housing and neighborhood commercial area. From the point of functional area structure and major facilities location, line-type commercial area is developed along the line of central axis route and access route to administrative district. Especially direction of the growth of commercial area is strongly connected with the interrelationship between the study area and its neighboring cities. Pattern of commercial district development is varied with the direction of matrix route. That is, commercial district, which shows one side development pattern along the East-West direction route, is developed on both sides of street along the South-North direction route.

  • 수도권의 도시화는 서울로의 교통 접근성의 변화에 따라 급속하게 진행되었다. 도시화 과정 속에 교외화, 주택 수의 증가, 도심용지 토지이용 증대 등의 다양한 공간적 변화가 이루어지고 있다. 본 연구의 목적은 2001~2008년 간 경기도 남양주시의 도시화 경관현상을 살펴보고 교통(도로 및 철도) 접근성의 변화에 따른 주변 토지이용 변화의 상관성을 분석하는데 있다. 상관성 분석 결과를 토대로 멀티 에이전트 시스템(MAS)을 이용하여 교통접근성과 토지이용 에이전트 간 상호작용의 관점에서 시뮬레이션 하였다. 이런 과정을 통하여 교통접근성의 변화로 인한 주변 토지이용 변화를 시공간적으로 예측하고자 한다. 도시화 현황을 살펴보기 위해서 위성영상 자료와 지적도 자료를 이용하여 거시적 미시적 경관 분석을 실시한 후 교통접근성의 변화에 따른 주변 토지이용 변화의 상관성을 분석하기 위해 교통자료와 토지이용 자료를 활용하여 GIS분석 및 통계 분석, 시뮬레이션 분석을 하였다. 본 연구를 통해 신규 도로 및 철도가 생성됨에 따라 주변 500m 이내에서 도심 토지용지로 변경되는 패턴을 확인할 수 있었으며, 향후 도로 및 철도가 생성됨에 따라 발생하는 토지용지 변화 현상을 예측할 수 있는 시스템을 구축하였다. 이를 통해 교통시설 입지 대상지역 선정 시 기초자료로 활용할 수 있는 근거가 될 수 있을 것으로 기대된다.
